On March 19, GM put a halt on Chevrolet Volt production in order to get rid of some of the older versions of the plug-in electric hybrid and make room for those with the recent battery fix. Also, new Volts with the changes made for the California market are making their way into the inventory.

The production halt was expected to last for four weeks. However, new reports show that Volt production will resume a few days earlier than planned. GM has already started notifying Detroit-Hamtramck plant employees, where the Volt is assembled.

It's a good time to bring Volt production back to life, since it seems that Volt popularity has risen recently. In March, U.S. Volt sales shot up to 2,289, which is its best month yet since release. Of that total, 2,129 were sold to retail customers while 160 were sold to fleet customers.

This surge in sales couldn't have come at a better time, either. The Volt had a difficult year throughout much of 2011 and during the beginning of 2012 due to problems with battery fires.

In May 2011, Chevrolet's Volt caught fire three weeks after a side-impact crash test conducted by the National Highway Traffic Safety Administration (NHTSA). The Volt was parked in a NHTSA testing facility in Wisconsin, and was so severe that it ended up catching nearby cars on fire as well. This led to an investigation into the safety of lithium batteries.

GM moved quickly, offering loaner vehicles to customers and even buying Volts back from scared owners. In January 2012, GM recalled 8,000 Volts off the road as well as another 4,400 for sale in showrooms to fix the batteries. The fix entailed the addition of steel to the plate that protects the EV's T-shaped, 400-pound battery. This aimed to prevent penetration into the battery in case of an auto accident, and would stop both coolant from leaking and would evenly distribute the force of a crash.
